Here's why:
* Acropolis (ἀκρόπολις) literally means "high city" in Greek. It refers to a fortified settlement built on a hilltop, often the highest point in a city or region.
* Strategic Importance: These hilltop settlements were strategically important for defense, offering a commanding view of the surrounding area and making them difficult to attack.
* Religious Significance: Acropolises often housed temples and other religious structures, making them important religious centers as well.
The most famous example of an acropolis is the Acropolis of Athens, home to iconic structures like the Parthenon.
